Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Sertoli cells
Concept:

The testis utilizes a specialized negative feedback mechanism to prevent the overproduction of sperm.

Solution:

  • Inside the seminiferous tubules, Sertoli cells facilitate sperm maturation.


  • When the rate of spermatogenesis is too high, these Sertoli cells release a peptide hormone called inhibin.


  • Inhibin travels to the anterior pituitary and specifically suppresses the release of FSH, slowing down sperm production.


Why other options are incorrect:

Leydig cells (also called interstitial cells) produce testosterone, which feeds back to inhibit LH, not primarily FSH. Hensen's node is an embryonic organizer structure.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
